Yes. My current car is the 'Sexy Scion', which is really sort of a ripoff of the name for my good friend in high school's car, the 'Sexy Saturn'. I have also owned, at one time or another, the Buck Truck, the Hearse and Red (who was, of course, red).
We name everything in my family. The ducks that visit our yard once a year. The little stone turtle in the garden. The autopilot on the boats (always named George).
